housing and the roller assembly slot. Figure E
W
ith pump setting on L, hold tube fitting and
jog roller assembly by turning pump on.
I
MPORTANT! Avoid rotating wrist, which can result in
a twisted tube that will not center. DO NOT force tube
and be careful of your fingers.
Guide tube with slight tension toward the
center to prevent pinching between housing
and roller assembly. If the tube is pinched
during installation, discard. Figure F
When tube reaches the discharge tube housing
slot, turn pump off.
Turn dial ring to setting 10, hold tube fitting
firmly, do not pull, and turn pump on.
NOTE: A used tube will have stretched
approximately 3/4" and the new tube will
appear to be stiff and short. Follow directions
to allow rollers to stretch tube into place.
Allow rollers to stretch tube into place while
guiding tube into slot. Figure G
Turn pump off.
Apply a small amount of AquaShield
to cover
bushing ONLY and replace cover and two
screws. Figure H Leave the front screw between
the tube fittings loose for centering the tube in
the next step.
IV CENTER NEW TUBE
To center pump tube on rollers, set feed rate dial to setting 10. Turn pump on.
Turn the tube fitting on the suction side not more than 1/8 of a turn in the
direction tube must move. Figure I
DO NOT let go of fitting until tube rides approximately in center of rollers.
Turn pump off, let go of fitting, and finger tighten cover screws.
Inspect the suction and discharge lines, point of injection, and check valve
duckbill for blockages. Clean all deposits and/or replace parts as required.
Failure to do so may lead to poor pump performance, including shortened
tube life. Reference your pump owner's manual for details.
Reconnect the suction and discharge lines.
NOTE: Cover screws are self-tapping and must be backed in to locate original thread
before securing. If a screw boss is stripped, use alternate bosses and position
opposite from each other. Never secure the cover plate with more than 2 screws.
TUBE CHANGE FOR FIXED OUTPUT PUMP
To install a new tube in a fixed output pump, follow the
instructions and utilize the on/off switch to jog the
roller assembly in the absence of the feed rate control.
I PREPARATION

Prior to service, pump water or a compatible buffer solution through the pump
and suction and discharge lines to remove chemical and avoid contact.
Turn pump off.

ixed Output Model
(manufactured before
04/29/11)
Only the Stenner fan
brake tool should be used for this step.
a. Insert the fan brake tool into the
vent in the rear of the motor housing.
Refer to the figures below.
NOTE: The fixed output pump
doesn’t have a clutch so the fan
brake keeps the shaft from rotating
when expanding the roller assembly.
b. Holding the pump securely, use the
cover as a wrench and quickly (snap)
rotate the roller assembly clockwise
to expand the roller assembly. The
tube will be pressed against the
tube housing wall. Figure N & O
NOTE: Clockwise is viewed from
facing the head of the pump.
c. Remove the fan brake tool. Proceed
to step 9.
Fixed Output Model
(motor vent with key slot,
manufactured after 04/29/11)
a. Slide one latch out to remove it
from the tube housing. Insert the
latch end into the key slot in the
vent in the rear of the motor
housing. While pressing the latch
into the rear of the motor, gently
rotate the cover clockwise until it
stops. Refer to the figures below.
b. Holding the pump securely, use the
cover as a wrench and quickly
(snap) rotate the roller assembly
clockwise to expand the roller
assembly. The tube will be pressed
against the tube housing wall.
Figure N & O
NOTE: Clockwise is viewed from facing
the head of the pump.
c. Remove the latch from the vent and
re-attach it to the tube housing.
Proceed to step 9.
IV CENTER NEW TUBE
Ensure the pump is off. Lift the latch located between the tube fittings, leaving the end of the latch engaged with the lip on the
tube housing cover. Leave the latch on the opposite side engaged. Figure R
Plug the pump in and turn it on. Turn the tube fitting on the suction side not more than 1/8 of a turn in the direction tube must
move. Figure S
DO NOT let go of fitting until tube rides approximately in center of rollers.
Turn the pump off, let go of the fitting, and secure the latch between the fittings. Figure T
For CE pump only: Reinstall the safety screw on the cover.
Inspect the suction and discharge lines, point of injection, and check valve duckbill for blockages. Clean all deposits and/or
replace parts as required. Failure to do so may lead to poor pump performance, including shortened tube life. Reference your
pump owner's manual for details.
Reconnect the suction and discharge lines. DO NOT allow tube fittings to turn inside the pump housing.
Turn the pump on and run for one minute to verify operation.
